As shown in FIG. 1, it is a functional block diagram of the health eye monitoring system 10 according to an embodiment of the present invention. In the present embodiment, the health eye monitoring system 10 is installed and operated in the electronic device 100. The electronic device 100 further includes, but is not limited to, a light sensor 20, a memory 30, an imaging device 40, a measuring device 50, a timer 60, a prompting device 70, and a processor 80.

The light sensor 20 is configured to sense an ambient light intensity, and the memory 30 is configured to store different size ranges of user pupils corresponding to different ambient light intensities at a normal visual distance, each size range including an upper limit and a Lower limit. The imaging device 40 is fixed at a position in front of the eye for capturing a pupil image of the user. Referring to FIG. 2 together, in the embodiment, the electronic device 100 is mounted on a frame of the glasses 200, and the camera device 40 is fixed at a specific position in front of the lens and aligned with the eye position of the user. In the present embodiment, the imaging device 40 is a CCD (Charge-Coupled Device). The measuring device 50 is for measuring the pupil size of the user from the pupil image of the user captured by the camera device 30, and the timer 60 is used for timing.

The health eye monitoring system 10 is configured to control the prompting device 70 to prompt the user to use the eye reasonably when the user uses the eye time for a short time for more than a predetermined time. In the embodiment, the prompting device 70 is a speaker, and the speaker prompts the user to use the eye reasonably by issuing a prompt tone.

In the embodiment, the health eye monitoring system 10 includes an acquisition module 11 , a determination module 12 , and a control module 13 . The module referred to in the present invention refers to a series of program instruction segments that can be executed by the processor 80 of the electronic device 100 and that can perform a specific function, and are stored in the memory 30 of the electronic device 100. The function of each module 11-13 will be specifically described in the flowchart of FIG. 3 below.

FIG. 3 is a flowchart of a health eye monitoring method according to an embodiment of the present invention.

In step S201, the control module 13 controls the camera device 40 to capture a pupil image of the user at a preset frequency.

In step S202, the control module 13 controls the measuring device 50 to measure the pupil size of the user from the pupil image of the user captured by the imaging device 40.

In step S203, the control module 13 controls the light sensor 20 to sense the current ambient light intensity.

In step S204, the acquisition module 11 acquires a pupil size range of the user under the normal visual distance from the memory 30 according to the current ambient light intensity.

Step S205, if the pupil size measured by the measuring device 50 is smaller than the lower limit of the pupil size range of the user under the normal visual distance, that is, the user is in the close eye state, the control module 13 The timer 60 is controlled to count.

In step S206, the determining module 12 determines whether the time counted by the timer 60 exceeds a preset time. If the timing time exceeds the preset time, step S207 is performed. In this embodiment, the preset time may be a scientific long-term use of the eye for a short distance, or may be a close-up eye time suitable for the user according to the characteristics of the eye.

In step S207, the prompting device 70 is controlled to prompt the user to use the eye reasonably. It is well known that if the eye distance is too long for a short distance, the eye fatigue will be caused. If the user's close eye time exceeds the preset time, the user is in a non-healthy eye state. At this time, the prompting device 70 prompts. The user pays attention to the health eye.

The health eye monitoring system 10 of the present invention can issue a prompt message when the user uses the eye for a long time, prompting the user to use the eye reasonably to protect the eye health of the user.
